Madonna's daughter LOURDES was starstruck when she met Harry Potter star EMMA WATSON - despite having the most famous mother in the world.

The nine-year-old Potter fan bumped into Watson, who plays HERMIONE in the magical movie series, at the London premiere of HARRY POTTER AND THE GOBLET OF FIRE earlier this month (07NOV05).

Madonna, who affectionately refers to her daughter as 'Lola', says, "In the middle of the movie, (Lourdes) had to go to the bathroom.

"Hermione was in there washing her hands and Lola's jaw hit the ground."
